This one looks good to me too, but let's give people until
Mon Apr 13th to comment on the change in gdbtypes.c. I believe
this is the simplest approach, and, to me, the fact that the
TYPE_TARGET_TYPE is currently only used by Ada doesn't make it
a problem for handling it in generic code. But if others object,
then we can use the hack you had in ada-lang before you came up
with this version of the patch (the hack is based on the fixed
version of the type having a backlink to the original type it fixed,
thus allowing us to verify whether the cached TYPE_TARGET_TYPE
was copied from another type and is therefore irrelevant to this
type).
